Kubereka ndi chiyani?
Zimbalangondo ndi zigawo zomwe zimathandizira tsinde, zomwe zimagwiritsidwa ntchito kutsogolera kayendetsedwe ka shaft, ndikunyamula katundu wochokera kumtengo kupita ku chimango. Ma bearings amagwiritsidwa ntchito kwambiri komanso amafunikira magawo othandizira ndi magawo oyambira pamakina. Ndizigawo zothandizira ma shafts ozungulira kapena magawo osunthika a makina osiyanasiyana, komanso ndi zigawo zothandizira zomwe zimadalira kugudubuza kwa matupi ogubuduza kuti azindikire kuzungulira kwa injini yaikulu. Amadziwika kuti ma mechanical joints.
Kodi ma bearings ayenera kugawidwa bwanji?
Malingana ndi mitundu yosiyanasiyana ya mikangano pamene magazini imagwira ntchito, zotengerazo zimagawidwa m'magulu awiri:
mayendedwe otsetsereka ndi mayendedwe ogudubuza.

Plain kubereka
Malingana ndi momwe katunduyo amayendera, zitsulo zotsetsereka zimagawidwa m'magulu atatu:①Radial bearing--kunyamula katundu wa radial, ndipo mayendedwe olemetsa amakhala pakatikati pa shaft;
②Kuthyola——kunyamula katundu wa axial, ndipo njira yolemetsa imayenderana ndi mzere wapakati wa kutsinde;
③Radial-thrust bear--nthawi imodzi imanyamula katundu wozungulira ndi axial.
Malingana ndi momwe mikangano imakhalira, mayendedwe otsetsereka agawidwa m'magulu awiri: zitsulo zosasunthika zopanda madzi komanso zotsekemera zamadzimadzi. Yoyamba ili mumkhalidwe wa kukangana kowuma kapena kukangana kwa malire, ndipo yotsirizirayo ili m'nyengo yamadzimadzi.
